How the visit works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to several days, depending on how many gaps there are. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work
- Keep pets and children clear of the area while we work

Fire rated sealant in Manor House, done properly
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and the gap is resealed with a product tested for that use. We work on flats & HMOs, linear gaps and service penetrations, and the jobs we see most are gaps where walls meet ceilings or slabs and fire stopping disturbed by later work.
London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, from washroom silicone to fire-rated sealant around pipes and cables passing through walls. Out-of-hours working can be arranged where a building in Manor House can’t close.
There’s a 12-month guarantee on every job, whatever its size.

What fire rated sealant looks like in Manor House
Manor House has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
As a London address, Manor House can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Community buildings like Church of St Olave are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

Common problems we fix in Manor House
In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.
Keep an eye out for these signs:
- Gaps filled with a product that isn’t fire-rated
- Fire seals that have cracked with movement
- Linear gaps at the head of walls
- Open gaps behind door architraves
Rented homes near Harringay Green Lanes station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

FAQs for Manor House
Is parking a problem for a job in Manor House?
Parking in Manor House, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
I let a flat near Harringay Green Lanes station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.
Do you offer different sealant colours?
Usually, yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you tell me how many minutes the seal will last?
We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Surface by surface
Linear gaps
Some linear gaps have to cope with movement as well as fire. The product and depth are chosen to suit both.
Flats and HMOs
Conversions normally leave a mix of old and new service holes. We seal the ones on your specification with a tested product and record where they are.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Store the list of sealed gaps with your building paperwork
- Include fire stopping when you schedule refits
- Don’t fill fire-stopping gaps with ordinary foam or silicone
- Check whether a sealant can be painted before decorating over it
Any fire seal that’s cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Why deal with it now?
Doing it once, properly, beats doing it twice. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Manor House.
